Answer:
(5.4k+7.9m+8.1n) centimeters
Step-by-step explanation:
Given the side length of a triangle;
S1 = (1.3k+3.5m) cm
S2 = (4.1k-1.6n) cm
S3 = (9.7n+4.4m) cm
Perimeter of the triangle = S1+S2 + S3
Perimeter of the triangle = (1.3k+3.5m) + (4.1k-1.6n) + (9.7n+4.4m)
Collect the like terms;
Perimeter of the triangle = 1.3k+4.1k+3.5m+4.4m-1.6n+9.7n
Perimeter of the triangle = 5.4k+7.9m+8.1n
Hence the expression that represents the perimeter of the triangle is (5.4k+7.9m+8.1n) centimeters
There is nothing here for anyone to work off, If you have a picture or screenshot that would be very nice!
I think the answer will be B. Hope it help!
Volume of a pyramid is (L * w * h) / 3
L=10 and w=10
h can be found by using the Pythagorean theorem:
divide the base by 2 and we get 5. Then we have that the hypotenuse is 13 and the bottom of the right triangle we formed is 5. a= sqrt(c^2-b^2)
a=h=12
we plug these numbers into the formula for the volume of a pyramid and get:
400
Answer: 6 times
Step-by-step explanation:
Let the Length of the rectangle be L and the Width be W
Also , let us pick the Length as the longest side , then from the statement
L = 2W
The perimeter of a rectangle is given as :
P = 2 ( L + W )
substitute L = 2W into the formula , we have
P = 2 ( 2W + W )
P = 2 (3W)
P = 6W
Therefore the Perimeter is 6 times as long as the Width
